Basically you special order your GT 4% below invoice then add either:
Stage 1 is $8500 installed (700hp)
Stage 2 is $9000 installed (750hp)
And you either pick it up at the dealer or have it shipped to your house like I'm doing. Looks like there will be some extra delay with the plants closing for several weeks. But the used car bubble is supposed to last all year and the value of my Mustang keeps going up while the price of a new GT stays the same so its actually a good thing right now.
